Hi there I have 3 questions on neurophysiology if anyone could help me out that would be great

1. Is a diminished or absent stretch reflex always linked to a pathological state? YES/NO

2. Briefly explain your answer to the question above.

3. With reference to neurophysiological basis, how is the knee jerk reflex response greater when carried out with a Jendrassik manoeuvre at the upper arm level than when no Jendrassik manoeuvre is carried out?

4. A patient shows the Babinski sign in their left leg but a normal plantar reflex in their right leg. With reference to a specific neural pathway indicate 2 points along the pathway where damage may occur that could account for this observation?
